Microbial production of acrylamide by nitrile hydratase

I have just obtained a copy of the "Acrylamide, Microbial Production by Nitrile Hydratase" by R-C Zheng, Y-G Zheng and Y-C Shen from the Encyclopedia of Industrial Biotechnology: Bioprocess, Bioseparation and Cell Technology, published in 2010; DOI: 10.1002/9780470054581.eib004. It is new, interesting resource for how much large scale use of NHases there is going on, and includes some information I havent seen anywhere else before.

• It gives a worldwide estimate for the biocatalytic production of acrylamide as 400,000 t/a
• There are "more than 10 plants" in China running microbial acrylamide production using a Nocardia strain to yield a total production capacity which "has exceeded 200,000 t/a", with plans to increase this to 300,000 t/a
• Degussa have a plant in Russia with a production capacity of 24,000 t/a using a R. rhodocrous M8 strain.
• Mitsui Chemical have a JV acrylamide plant in Pusan, Korea.
• SNF Floerger built a 20,000 t/a plant using the Nitto technology in 1999 (but it doesnt say where), and have plans for a further 5 of the same size.
